USING THE 100ID SERIES
Z
control is Zoom. Zoom allows
selection of various ranges for full
screen viewing. By using the
display to view a smaller area, the
effective display resolution is
increased, and the units ability to
separate targets close together is
enhanced.
The zoom range is determined by
the depth range in use when
Zoom is enabled. In shallow water,
when the 15' or 30' depth range is
used, the zoom range will be 15'.
If the 60' or 120' depth range is in
use, the zoom range will be 15', if
a 180' to 480' depth range is used,
the zoom range will be 30', and if
the 600' range is in use, the zoom
range will be 60'.
Pressing the UP or DOWN arrow
button enables zoom and adjusts
the zoom 'window' to the desired
depth. The upper and lower limits
are shown on-screen and the digi-
tal depth readout will continue to
track the bottom even when
Zoom is enabled.
To disable Zoom press the UP
arrow button until Zoom turns off.
